Description
Technical Field
The utility model relates to a mine engineering machine tool technical field specifically is a connection structure of bucket, quartering hammer and forearm suitable for brokenly dig dual-purpose entry loader.
Background
In mining and tunneling at the present stage, blasting or special crushing equipment is mainly adopted for tunneling operation, and then the crushed materials are transported and constructed. However, as the national regulations on explosives become stricter, the cost of blasting is higher. For construction sites which do not allow blasting operation, special tunneling and transferring equipment is required. For a construction site with a relatively small mining or tunneling section, the transfer and switching among devices are relatively difficult, so that the time is delayed, and the investment cost of the devices and manpower is increased. Therefore, it is necessary to develop a device integrating crushing, tunneling, excavating and loading, and the connection structure of the bucket, the breaking hammer and the small arm is an important link.

In order to realize the purpose, the front end of the conveying and unloading mechanism of the utility model is provided with a telescopic breaking and digging integrated tunneling mechanism; the front end of a small arm of the telescopic breaking and digging integrated tunneling mechanism is respectively hinged with a digging bucket and a connecting rod, a connecting plate is hinged between the connecting rod and the digging bucket, guide shafts are arranged on two sides of the upper portion of the small arm, a sliding rail is arranged in the small arm and is tightly matched with the guide shafts through a notch in the sliding rail, and a hydraulic breaking hammer is clamped between the two sliding rails.
A bucket oil cylinder and a breaking hammer oil cylinder are arranged in the small arm; the cylinder end of the bucket cylinder is connected with the small arm, and the piston rod end is connected with the connecting rod; the cylinder end of the breaking hammer oil cylinder is connected with the small arm, and the piston rod end is connected with the sliding rail.
The section of the main body after the small arm is formed is in a convex shape, and the section of the main body after the large arm is welded and formed is rectangular; the big arm is hinged on a revolving body of the conveying and discharging mechanism, the front end of the big arm is hinged with the small arm, a big arm oil cylinder is arranged between the revolving body and the big arm, and a small arm oil cylinder is arranged between the big arm and the small arm
Compared with the prior art, the utility model, through integrated high-power hydraulic breaking hammer on the forearm with take off dress mechanism, make it have broken tunnelling simultaneously and take off dress material loading function, realize a tractor serves several purposes, can effectively reduce construction cost, improve tunnelling efficiency of construction, can not only effectively alleviate mining exploitation to the reliance of blasting, can also reduce exploitation, tunnelling cost, improve production efficiency.
